RDoc::Generator::HTML

We’re responsible for generating all the HTML
files from the object tree defined in code_objects.rb. We generate:

files

an html file for each input file given. These input files appear as objects
of class TopLevel

classes

an html file for each class or module encountered. These classes are not
grouped by file: if a file contains four classes, we’ll generate an html
file for the file itself, and four html files for the individual classes.

indices

we generate three indices for files, classes, and methods. These are
displayed in a browser like window with three index panes across the top
and the selected description below
